复制代码 代码如下:

<mx:DataGrid id="dg" click="select()" dataProvider= "{modelLocator.resultList}" border

verticalGridLines="false" horizontalGridLines="false" verticalScrollPolicy="off" rowCount="10"

fontSize="16" font fontThickness="0" width="100%" height="100%">

<mx:columns>

<mx:DataGridColumn dataField="programName " headerText="节目名称" >

<mx:itemRenderer>

<mx:Component>

<mx:HBox width="100%" height="100%" horizontalAlign="left" verticalAlign="middle" horizontalScrollPolicy="off" verticalScrollPolicy="off">

<mx:Script>

<![CDATA[

import mx.controls.Alert;

override public function set data (value:Object):void

{

if(value != null)

{

super.data = value;

programXYZ.htmlText = data.programName;

//Alert.show(this.programXYZ.text);

}

}

]]>

</mx:Script>

<mx:Text id="programXYZ" />

</mx:HBox>

</mx:Component>

</mx:itemRenderer>

</mx:DataGridColumn>

</mx:columns>

</mx:DataGrid>

关键是重写了 override public function set data(value:Object):void 方法
